A photo from Europe's Copernicus Sentinel-2 satellite shows two gargantuan cracks forming along the edge of Antarctica's Pine Island Glacier, one of the fastest-shrinking glaciers on the continent. A huge iceberg just broke off Antarctica's Pine Island Glacier After all, if you were a Boltzmann Brain, everything that you could come up with to prove or disprove it would likely be because of the hallucinations your consciousness is having.

Other types of solipsistic thinking have also entered our culture. We know that generally things tend to fall apart and decay.

What the influential Austrian physicist Ludwig Boltzmann (1844-1906), one of the founders of the field of thermodynamics, hypothesized is that while the entropy of a system (its measure of disorder) always increases (moving towards disorder), there is some tiny possibility that a fluctuation can bring a system from disorder to order. By ". Around this time, Pine Island Glacier started to shed smaller icebergs more frequently. worrisome on the heels of the above UN IPCC report, which basically tells us we're screwed unless we take drastic action—and, I mean drastic—in order to curb emissions and slow the inexorable drift into an Earth that looks like one of those terrifying science fiction novels. NY 10036. Vote like your lives depend on it, folks. As a result, the Pine Island and Thwaites ice shelves are retreating inland faster than new ice can form. “Although iceberg ‘calving’ from floating Antarctic ice shelves is a natural, ongoing process, the recent calving event of Pine Island Glacier was particularly large and such calving events from this glacier appear to be becoming more frequent,” says Alison Banwell, a glaciologist at CIRES, University of Colorado, Boulder. Calving Icebergs Pine Island Glacier ice shelf periodically calves huge icebergs. By July 2013, infrared and radar images indicated that the crack had cut completely across the ice shelf to the southwestern edge. It may be more likely for a Boltzmann Brain to come into existence than the whole Universe. On Thursday (Feb. 6), temperatures near a research base on the continent's northern edge reached 64.9 degrees Fahrenheit (18.3 degrees Celsius), the World Meteorological Organization reported. 2040 J. E. Arndt et al. From Oct 2014 to recent calving in 108 #sentinel1 images @CopernicusEU @ESA_EO pic.twitter.com/oYKvelCKPd. Two large rifts in PIG were spotted in 2019 and scientists have kept a close eye on the cracks and changes. In this video, Michael Pollan, Sam Harris, Jason Silva and Ben Goertzel discuss the history of psychedelics like LSD and psilocybin, acknowledge key figures including Timothy Leary and Albert Hoffman, share what the experience of therapeutic tripping can entail, and explain why these substances are important to the future of mental health.

The collected data will help health professionals develop better models for predicting who's most at risk of gun violence. Pine Island Glacier Calving (WMS) The Pine Island Glacier is the largest discharger of ice in Antarctica and the continent's fastest moving glacier. pic.twitter.com/iubE8JffVRFebruary 10, 2020. The Caltech theoretical physicist Sean Caroll called them "cognitively unstable: they cannot simultaneously be true and justifiably believed" in his 2017 paper "Why Boltzmann Brains Are Bad. Scientists worry that this persistent retreat could be a sign that a runaway melting cycle is in effect: As comparatively warm sea water laps at the newly exposed edges of an ice shelf, melting accelerates, the ice shelf stretches and thins, and further calving becomes ever more likely. Are you a Boltzmann Brain? 2018: B-46 How they work is not completely understood, but the empirical evidence shows promise in the fields of curbing depression, anxiety, obsession, and even addiction to other substances. There was a problem. Abstract. Pine Island Glacier, along with its neighbour Thwaites Glacier, connect the centre of the West Antarctic Ice Sheet with the ocean – together discharging significant quantities of ice into the ocean. 1901

From the physicist's work it follows that it would be more likely for random quantum fluctuations in nature to create something simpler than our astounding Universe – for example, a self-aware entity that believes it is a person in a world full of people, history, and particular physics. Re: Pine Island Glacier (PIG) Calving and Discussion « Reply #2593 on: November 18, 2020, 03:57:37 PM » I post an animation based on the SIS images of 06/11, 12/11 and 18/11 to show the rapid evolution of WmR4 (especially in the last 6 days).

"

In the study, all conversations about firearm access and exposure will be confidential. According to NASA, the region around the two glaciers contains enough vulnerable ice to raise the ocean by 4 feet (1.2 meters). The Pine Island glacier in #Antarctica has finally calved, creating many large icebergs! “The growing indentation into the shear margin was likely a factor in the formation of all the rifts that then caused PIG’s ice to fall apart in the last calving. These two glaciers have been losing ice over the last 25 years. Boltzmann Brains are hypothetical disembodied entities with self-awareness.

"This will be the first research study to universally screen all patients who come into the emergency department for firearm access, and gun violence risk, and then intervene as needed, with gun safety counseling, gun locks, community resources, and medical referrals," said Dr. Chethan Sathya, director of Northwell's Center for Gun Violence Prevention. It also has us, humans, nature's supreme creations (at least according to us). The irreversible collapse of the West Antarctic ice sheet would raise sea levels 20 feet, says the UN. New York, Scientists think the change in calving frequency is likely related to the thinning of the ice shelf. Over the past 8 years, the Pine Island glacier is losing about 58 billion tons of ice per year. Because ice at the edge of the glacier was already floating, this ice will not directly contribute to sea level rise when it inevitably melts. There is nothing really there but your self-awareness.

These types of entities have been dubbed "Boltzmann Brains" by modern physicists Andreas Albrecht and Lorenzo Sorbo. They did not claim to such brains really being in existence but rather used the idea to point out the absurdities and limitations of taking the idea of thermodynamic fluctuations to their extent.

Boltzmann Brains have also been criticized as philosophical paradoxes that are experientially unprovable. Recently, the frequency of Pine Island Glacier calving events has increased. Live Science is part of Future US Inc, an international media group and leading digital publisher. Gun violence is a public health crisis that is notoriously difficult to study because of politics. That's the 2017 calving, in a GIF created by Stef Lhermitte. Large calving events used to take place at Pine Island Glacier every four to six years, but they’re now a nearly annual occurrence. Mortality rate vs funding for 30 leading causes of death in the United States. The goal is to encourage firearm safety, educate at-risk patients on violence-prevention resources, and normalize doctor-patient conversations about guns—not stigmatize gun ownership or infringe upon individual rights.

This is of particular concern in the case of Pine Island and Thwaites Glaciers and adjacent glaciers in the Amundsen Sea sector of the West Antarctic Ice Sheet. The reality of climate change: 10 myths busted, Epic time-lapse shows what the Milky Way will look like 400,000 years from now, Watch SpaceX test a giant 'Starship' over Texas today [UPDATED], Archaeologists find vast network of Amazon villages laid out like the cosmos, Sprawling 8-mile-long 'canvas' of ice age beasts discovered hidden in Amazon rainforest, The strange story of how nuns uncovered 'House of Jesus' in Nazareth. While large calving events used to occur at Pine Island Glacier every four to six years, they've now become a near-annual occurrence, according to NASA. There is a lot we don't know about psychedelics, but what we do know makes them extremely important. It was mapped by the United States Geological Survey (USGS) from surveys and United States Navy (USN) air photos, 1960–66, and named by the Advisory Committee on Antarctic Names (US-ACAN) in association with Pine Island Bay. Calving events have occurred in … The Pine Island glacier "is one the fastest-retreating glaciers in Antarctica." But all this amazing amount of varied matter is also very hard to pull off, requiring a tremendous amount of energy. A large iceberg has finally separated from the calving front of Antarctica's Pine Island Glacier. Pine Island Glacier is the largest current Antarctic contributor to sea-level rise. Scientists find routes using arches of chaos that can lead to much faster space travel. Dr. Sathya and Mr. Dowling are spearheading Northwell's gun-violence prevention efforts, including the "We Ask Everyone. Related: Today’s climate change is worse than anything Earth has experienced in the past 2,000 years. The close up shows a piece of pottery next to burned pieces of wood. The goal is to destigmatize doctor-patient conversations about guns, and reframe gun violence as a public health issue.

Doctors often ask patients about the health risks in their daily lives, such as sugar intake or tobacco use. The calving mechanism of tabular icebergs is one of the major unknowns in glaciology and hence calving events at locations where the glaciological variables of ice shelves or ice tongues are well known are ideal natural setups for studying these mechanisms. It's got planetary bodies of various shapes and sizes.

,
When we reframe [gun violence] as a public health issue, then we're able to use the same strategies that we've used to decrease car-crash deaths, decrease infections and deaths from HIV, and reduce injuries and deaths from a host of other problems.

The paradox of the Boltzmann Brain can really pull the rug from under you if you follow it to all of its logical and illogical extents. Specifically, the accompanying image (from the website) illustrates how rifting (cracking) of the Pine Island Ice Shelf, PIIS, has increased from 1973 to 2011, while comparing the shape of the 2011 calving face with the current calving face (see prior posts in this thread), shows how rapidly the calving has accelerated in the past two years (as compared to the 1973 to 2011 period). “When Pine Island Glacier lost contact with the thicker ice of the southwest tributary it was like the loss of protection on the glacier’s flank,” said NASA/UMBC glaciologist Christopher Shuman. Scientists at Copernicus, the European Union’s Earth observation program, have been closely monitoring the glacier since large cracks appeared near its edge in October 2019. Scientists first detected a rift in the glacier in October 2011 during flights for NASA's Operation IceBridge. PIG) The area of the iceberg poised to calve off the Pine Island Glacier is about 115 square miles, or 300 square kilometers. The Pine Island Glacier (a.k.a. If the West Antarctic ice sheet collapses, it will mean a 20-foot rise in sea levels. But such a person - let's say you - is only full of all the knowledge and experiences because you are made that way by the fluctuation that created you. Events like these may become all too common in the future, as fracturing and weakening of the ice increases. Carbon dating allows us to know exactly when ice was melted for drinking water in pre-Columbian America. Pine Island's newest icebergs calved just days after scientists reported the hottest temperature ever recorded in Antarctica. © The glacier ice streams flow west-northwest along the south side of the Hudson Mountains into Pine Island Bay, Amundsen Sea, Antarctica. This mind-churning idea proposes that the world is quite possibly just an effect of your disembodied consciousness and doesn't really exist. Photo by Mario Tama/Getty Images. "As the planet warms from 1.5°C to 2°C, the risks grow rapidly for some very dangerous tipping points, including the irreversible collapse of the West Antarctic ice sheet (which would raise sea levels 20 feet)," reads the UN's recent IPCC Report. The idea highlights a paradox in thermodynamics. This is doubly worrisome on the heels of the recent UN climate change report, which gave humanity an urgent deadline to cut carbon emissions: just 12 years. "If you look at any other public health issue, it starts with this universal type of approach.

The answers will become part of a large, anonymized data pool that will help researchers better understand the underlying factors behind gun violence. Can hospitals prevent gun violence? About one year ago, in Antarctica, the Pine Island Glacier By gathering data on changes to ocean temperature and increasing surface melt rates, researchers are working toward implementing the physics of calving—a calving law—in computer simulations. Stay up to date on the coronavirus outbreak by signing up to our newsletter today. Credit European Space Agency Pine Island Glacier (PIG), in the West Antarctic Ice Sheet, has an area of 175,000 square kilometres and loses about 45 billion tons of ice each year. That could set off unstoppable retreat of Pine Island Glacier.
